BUILDING MATERIALS

Hempcrete is carbon negative. The combination of hemp and lime (hempcrete) results in a soundproofing system and insulation superior to concrete.Unlike fiberglass or drywall, hempcrete is nontoxic and mold-resistant.It's good looking and 100% recyclable, hempcrete is as versatile as it is sustainable. It can be used in a mind-boggling array of applications from roof insulation to wall construction to flooring. Hempcrete is waterproof, fireproof, insulates well, does not rot [when used above ground] and is completely recyclable. It lacks the brittleness of concrete and consequently does not need expansion joints.

​​Hemp homes are the future of green living. Hemp builds stronger and healthier homes. One hemp home in Japan is estimated to be over 300 years old.

People who suffer from asthma, allergies or Multiple Chemical Sensitivity (also known as MCS, environmental illness, idiopathic environmental intolerance or total allergy syndrome) may be completely cured of some or all of their ailments by living in a clean-air, toxin-free home.

Hemp is the hope for the next generation. Sustainable practices for consumer and commercial products will soon be a requirement. In less than 3 short years, France will ban plastics in 2020.

Nearly all chemical constituents of an average house - plastics, synthetic fibers, carpeting, glue/resin, paints, petroleum products, etc. - can be replaced altogether by hemp-based products, completely eliminating common chemicals from your living space.​

Fiber boards made from a hemp-based composite is stronger and lighter than those made from wood. Hemp particle board may be up to 2 times stronger than wood particleboard and holds nails better. One acre of hemp produces as much cellulose fiber pulp as 4.1 acres of trees, making hemp a perfect material to replace trees for pressed board, particle board, and concrete construction molds.​

HEMP FIBER: A BUILDERS DREAM

The result is a lightweight insulating material ideal for most climates as it combines insulation and thermal mass.Hemp-foundation homes are ecologically appropriate because they are inexpensive, and can be prepared on site using only a cement mixer, and the material would be cheap and abundant. Foundation floors can be made in much the same way as the foundation. Hemp resists seepage, and so hemp cement is applicable for pouring onto a soil base to make a foundation floor. The floor insulation hardens into a solid mass which will not shift under pressure.

The typical compressive strength is around 1 MPa, around 1/20 that of residential grade concrete. It is a low density material and resistant to crack under movement thus making it highly suitable for use in earthquake prone areas. Hempcrete walls must be used together with a frame of another material that supports the vertical load in building construction, as hempcrete's density is 15% that of traditional concrete.

​•Hemp fiber increases tensile and compressive strengths, reduces shrinkage and cracking, similar to rebar or fiberglass.•Hemp hurds are also uncommonly rich in silica.• When mixed with lime, hemp hurds change from a organic product to a mineral. As a mineral state it is often referred to as hemp stone.
